How To Open A Can Without A Can Opener

There are two easy ways to open a can of food without a can opener. My wife didn’t believe me when I told her this would work.

The first way is to rub the top of the can in a circular motion against a piece of rough concrete (like a parking bumper or even a strip of sidewalk). However– it makes a lot of noise, and in a SHTF scenario I don’t like the idea of eing outside broadcasting to everybody around that I’ve got a can of food.

In a perfect world, you’d have a can opener on your knife or keychain.

But what if you don’t?

This method makes a lot more sense that the concrete method:

Of course, it wouldn’t hurt to keep a couple dozen of these lying around… would it?
